Answer:
Step-by-step explanation:
here you go mate :)
step 1
2(x + 4) = -6 solving for x
step 2
2(x + 4) = -6 simplify by distributing
2x+8=-6
step 3
2x+8=-6 subtract 8
2x=-14
step 4
2x=-14 look for the number that can divide them both like 2
2x/2=-14/2
answer
x=-7
Answer:
Cost of a pound of chocolate chips: $3.5
Cost of a pound of walnuts: $1.25
Step-by-step explanation:
x - cost of a pound of chocolate chips
y - cost of a pound of walnuts
We create two equations based on the information we have:
3x+2y=13
8x+4y=33
The whole point of these problems os to get rid of x or y. In this question, we can do this by multiplying both sides of the first equation by 2, and then subtracting it from the second equation:
8x+4y=33
6x+4y=26
2x=7
x=3.5
Then we change x for 3.5 in the first equation:
3×3.5+2y=13
10.5+2y=13
2y=2.5
y=1.25
Hope this helps!
